Opening arrangement for a vehicle door

Abstract

An opening arrangement is known for a vehicle door has a door lock which can be operated by an exterior door grip arranged on the outside on the exterior vehicle shell, which exterior door grip is movably disposed by a bearing bow fixed on the interior side on the exterior door shell. The bearing bow is supported on an end area, viewed in the longitudinal direction of the vehicle, by way of at least one deformation-resistant torsion support on the interior door shell and is fixed on the opposite end area, viewed in the longitudinal direction of the vehicle, on a door-fixed support part.

What is claimed is:  
     
       1. Opening arrangement for a vehicle door, having an exterior door shell as well as an interior door shell and having a door lock which can be operated by an exterior door grip arranged on the outside on the exterior door shell, which exterior door grip is movably disposed by a bearing bow fixed on the interior side on the exterior door shell, 
       wherein the bearing bow is supported on the interior door shell proximal to a first end area of the exterior door grip, viewed in a longitudinal direction of a vehicle, by way of at least one deformation-resistant torsion support, and is fixed proximal to a second end area of the exterior door grip situated on the opposite side of the first end area in the longitudinal direction of the vehicle on the door lock.  
     
     
       2. Opening arrangement according to claim  1 , wherein the torsion support is fastened on the interior door shell by at least one supporting head. 
     
     
       3. Opening arrangement according to claim  2 , wherein the torsion support is applied to the bearing bow eccentrically and on one side such that torsion forces onto the bearing bow because of a deformation of the exterior door shell can be transmitted without any torsion-caused deformation of the bearing bow to the torsion support and to the interior door shell. 
     
     
       4. Opening arrangement according to claim  3 , wherein the torsion support is disposed on the bearing bow by a supporting section permitting at least two different supporting angles relative to the bearing bow. 
     
     
       5. Opening arrangement according to claim  2 , wherein the torsion support is disposed on the bearing bow by means of a supporting section permitting at least two different supporting angles relative to the bearing bow. 
     
     
       6. Opening arrangement according to claim  2 , wherein the torsion support is oriented to be inclined at least once in the space between the interior and exterior door shells. 
     
     
       7. Opening arrangement according to claim  1 , wherein the torsion support is applied to the bearing bow eccentrically and on one side such that torsion forces onto the bearing bow because of a deformation of the exterior door shell can be transmitted without any torsion-caused deformation of the bearing bow to the torsion support and to the interior door shell. 
     
     
       8. Opening arrangement according to claim  7 , wherein the torsion support is disposed on the bearing bow by a supporting section permitting at least two different supporting angles relative to the bearing bow. 
     
     
       9. Opening arrangement according to claim  8 , wherein the torsion support has two supporting heads which are aligned with one another in a fork-type manner and of which one is provided for the arrangement of the torsion support in a left vehicle door and the other is provided for the arrangement in a right vehicle door. 
     
     
       10. Opening arrangement according to claim  1 , wherein the torsion support is disposed on the bearing bow by a supporting section permitting at least two different supporting angles relative to the bearing bow. 
     
     
       11. Opening arrangement according to claim  10 , wherein the torsion support has two supporting heads which are aligned with one another in a fork-type manner and of which one is provided for the arrangement of the torsion support in a left vehicle door and the other is provided for the arrangement in a right vehicle door. 
     
     
       12. Opening arrangement according to claim  1 , wherein the torsion support is oriented to be inclined at least once in the space between the interior and exterior door shells. 
     
     
       13. Vehicle door and door lock assembly comprising: 
       a vehicle door including an exterior door shell and an interior door shell which are spaced from one another,  
       an exterior door grip arranged outside of the exterior door shell,  
       a bearing bow fixed to an interior side of the exterior door shell and operable to support the door grip and facilitate transfer of door unlocking movements between the door grip and a door lock adjacent a first position of the bearing bow, and  
       a deformation resistant torsion support interposed between a second position of the bearing bow and the interior door shell, said deformation resistant support being configured and disposed to limit transfer of vehicle collision induced deformation of the exterior door shell to said second position of the bearing bow to thereby limit collision induced unlocking of the door.  
     
     
       14. Vehicle door and door lock assembly according to claim  13 , wherein the torsion support is fastened on the interior door shell by at least one supporting head. 
     
     
       15. Vehicle door and door lock assembly according to claim  13 , wherein the torsion support is applied to the bearing bow eccentrically and on one side such that torsion forces onto the bearing bow because of a deformation of the exterior door shell can be transmitted without any torsion-caused deformation of the bearing bow to the torsion support and to the interior door shell. 
     
     
       16. Vehicle door and door lock assembly according to claim  13 , wherein the torsion support is disposed on the bearing bow by a supporting section permitting at least two different supporting angles relative to the bearing bow. 
     
     
       17. Vehicle door and door lock assembly according to claim  16 , wherein the torsion support has two supporting heads which are aligned with one another in a fork-type manner and of which one is provided for the arrangement of the torsion support in a left vehicle door and the other is provided for the arrangement in a right vehicle door. 
     
     
       18. Vehicle door and door lock assembly according to claim  13 , wherein the torsion support is a unitary one-piece member. 
     
     
       19. Vehicle door and door lock assembly according to claim  18 , wherein the interior door shell includes a protruding supporting web engageable in an opening at one end of the one-piece member, and 
       wherein the door shell includes a protruding support member engageable in an opening at an opposite end of the one-piece member.
